Ground fault sensors help protect people, products,and processes from damage by ground fault conditions by monitoringall current-carrying conductors in grounded single- and three-phasedelta or wye systems. They provide a contact output that can operaterelays, contactors or signal automation systems.Note that this manual only covers solid state versions of the EGFSeries (listed in the table to the left). For installation manualscovering other models in the EGF Series family, please contactEaton’s Cutler-Hammer Sensor Application Engineers.QUICK INSTALL GUIDEThe below steps can be followed to quickly install a CurrentWatch™EGF Series switch.1. Run all current carrying conductors through sensor window, usingan auxiliary current transformer if conductors do not fit2. Mount the sensor to a surface if needed3. Connect output and power wiringa. Use up to 14 AWG copper wiresb. Ensure power and load matches those shown on the sensorlabel4. Test the unita. Pressing the “TEST” button will test the sensor’s internalcircuits (CAUTION: The output and any connected loads willswitch during the test process)INSTALLATION AND WIRINGConsiderations for installing and wiring EGF Series sensors…• Run wire to be monitored through the aperture (opening) in theswitch body, making sure all wires are oriented so that currentfl ows in the same direction (see “Principal of Operation” sectionon reverse side)• These sensors can be located in the same environment as motors,contactors, heaters, pull-boxes and other electrical enclosures• Mounting can be done in any position or hung directly on a wirewith a wire tie• Be sure to leave at least one inch distance between sensor andother magnetic devices• Connect power and output wiring to the sensor, using up to 14AWG copper wire and tightening terminals to 7 inch-pounds torque• Make sure the power supply matches the power rating on thesensor label• Make sure the output load is less than or equal to the output ratingon the sensor labelPower OutputGXControl Power(Match Sensor Rating--See Label)TEST(+)(-)Power Supply LED Contact Status LEDLoadContactor, Relay, Shunt Trip Breaker...(Do Not Exceed Rating--See Label)Setpoint AdjustFactory Calibrated and Covered(Remove Cover, Adjust andRelabel if Required)Output Power(Match Sensor Rating--See Label)For DC Output Versions...Observe PolarityInstallation InstructionsCurrentWatch™ EGF Series Ground Fault Sensors120V AC Powered, N.O. or N.C., Solid State Relay OutputP51925 Rev 02Effective: August 2007 Page 1WARNINGQuestions?
